The court's power to punish disobedience of its own orders - the mechanism that makes a court order more than a piece of paper.
Contempt is how a court enforces itself. Without it a court order would be advice. The power reaches conduct that disrupts proceedings and, far more commonly in ordinary life, failure to comply with an order the court has already made - to pay support, to hand over property, to allow parenting time, to produce documents, to stop doing something.
The central distinction is between civil and criminal contempt, and it is not about how serious the conduct was. Civil contempt is coercive: its purpose is to obtain compliance, and the classic formulation is that the person held in contempt "carries the keys of the prison in their own pocket" - the sanction ends when they comply. Criminal contempt is punitive: it punishes a completed act of defiance, the sentence is fixed, and complying afterwards does not undo it. Because criminal contempt is a punishment, it brings substantially greater procedural protections, and a sufficiently serious charge can carry a right to a jury trial.
Inability to comply is generally a defence to civil contempt, and this is the point of greatest practical consequence. A person who genuinely cannot pay is, in most systems, not in civil contempt for not paying - the sanction is meant to coerce someone who is able to comply and refuses. But the burden of raising and substantiating that inability normally sits on the person facing the motion, and a person who simply does not appear will not have raised it at all.
Contempt proceedings for non-payment of support or fines are also where people most often face jail without a lawyer. The Supreme Court has held that there is no automatic right to appointed counsel in every civil contempt case, but that where the state is not represented and the person's liberty is at stake the procedure must include safeguards - notice that ability to pay is the critical issue, a form to set out finances, and an express court finding on it.
Being served with a contempt motion is one of the strongest reasons to get a lawyer quickly, because jail is genuinely on the table in a way it is not elsewhere in civil litigation, and because the defence that usually matters - that you were unable to comply rather than unwilling - has to be raised and evidenced by you. Do not skip the hearing: non-appearance is the single worst response and can itself lead to an arrest warrant. If the order has become impossible to comply with because your circumstances changed, the right move is usually to apply to modify it rather than to wait until non-compliance is the subject of a motion.
